Since Down syndrome isn't a sex-linked trait, it won't be passed down from parent to child, and it has nothing to do with the genetics of the previous generations. Getting Down syndrome happens by a "mess up" in reproduction, not from getting it from previous generations.

∙ 12y agoThe genotype of Down Syndrome is Trisonmy 21. It is caused when there is a nonjusduction in the choromsome in meiosis. (During meiosis, the chromosomes don't separate correctly). A person with Down Syndrome has three choromsomes in the 21 pair. Hopefully, that's what you wanted.

∙ 14y agoA gene is not responsible for Down Syndrome; rather, a process called nondisjunction results in an extra chromosome in the 21st pair (trisomy 21) in meiotic division.

Are women responsible for the Down syndrome disease?
No
What is the focus of the research being done on Down syndrome?
From the Down Syndrome Research Center of Stanford University:It is known for causes the disorder. It's the increased activity of the extra genes on chromosome 21. Unlike other disorders, where genes are mutated or missing, in Down syndrome there are just too many copies of particular genes. The task of identifying the genes that cause Down syndrome, and trying to shut off the activity of the extra genes, is in theory much simpler than trying to fix a mutated gene or trying to add one that is missing.See the Related Link to the Down Syndrome Research Center of Stanford University.
Is it true to state that female only are responsible for down syndrome?
no and waverer some kids have down syndrome
Is Down Syndrome the same as Marfan Syndrome?
No. Down is caused by an extra chromosome while Marfan is due to a mutation in one or more genes.
What genes are responsible for neuronal migration disorders?
The most well characterized genes include DCX on the X chromosome, responsible for double cortex syndrome, and LIS1 on chromosome 17, the first gene identified for lissencephaly.
What is the most common cause for down syndrome?
Down's syndrome is a disorder caused by defective genes. It is most commonly caused by parents who are elderly at the time of birth.
Is it possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder please explain why?
Since Down Syndrome is not genetic and is a trisomy, dominant and recessive genes do not play a role and it is possible for two down syndrome parents to have a child without down syndrome.
Is Down syndrome caused by single or multiple genes?
it's the duplication of the 21st chromasome
Why is Down syndrome physical?
Down syndrome is a genetic condition that not only affects the brain but also affects physical appearance because of the genes affected by the disease. Sorry I don't know how exactly the genes are distorted. But they affect physical appearence.
Does Hannah Gosselin have down syndrome?
No she does not. The prominence in the foreheads of most of the children is caused by the inherited Asian genes from the father.
Does keenan cahill have down syndrome?
He may but it's more likely that he has Costello Syndrome, a very rare condition that affects the genes and it causes deformed hands, short stature, and deformity of the face, which fits him very well. It looks like he may have Costello Syndrome instead of Down Syndrome but I could be wrong
What are the genes responsible for the characteristics?
Genes are transcribed to make Proteins
